Consider the following.f(x) =3x³+ 20x²36x+ 16

Exercise (a) List the possible rational zeros off. Step 1 Since the function has integer coefficients, you can use the Rational Zero Test.

Possible rational zeros =factors of constant term/factors of leading coefficient

First, list thepositivefactors of the constant term. Remember to include 1 in your list of factors. (Enter your answers as a comma-separated list.)

(b)Sketch the graph offso that some of the possible zeros in part (a) can be disregarded.

(c)Determine all real zeros off.
